Anti-Inflammation effect of Genistein and Daidzein on Oxidised Low-Density Lipoprotein-Stimulated Human Coronary Artery Endothelial Cells / Lina Izzati Amer

Oxidised low-density lipoprotein (OxLDL) exerts adverse reaction to the endothelial cells in chronic oxidative disorder like atherosclerosis. Adhesion molecules such as VCAM-1 and ICAM-1, are regarded as key inflammatory markers promoting the endothelial cell injury, whereas nitric oxide regulates t...
